Dealing with Blackfly and Rosemary Beetles

on

The sun has absolutely been blazing over the last couple of weeks, so this has meant a lot of running around with watering cans desperately trying to save the plants that are waiting to be planted out; the plants that can’t be planted out because the ground is like concrete; and the plants that are planted out and roasted.

Blackfly on the Courgette plants

Today, whilst on my watering can round (i need a hosepipe, don’t i?), I spotted some familiar friends have arrived to celebrate what looks like a bumper crop from my Courgette ‘Black Beauty’ plants.

On the flower buds were the little black things, with the occasional ant running around. Yes, it’s the blackfly!

I’ve already had these visiting my Tomato ‘Minibel’ plants, but they’ve now migrated to the four courgette plants in my raised bed (the other two are a few metres away, but have a companion plant by luck).

I’ve not suffered with slugs and snails in this raised bed, and I’m wondering whether this is because i put some copper tape around most of it, or whether it’s because the wood of the bed is pretty rough. Either way, this doesn’t stop blackfly, but it would mean it’s a good place to plant the protective Marigold French ‘Orange’ plants – cheap and cheery – and something the blackfly don’t like. This seems to have helped the tomatoes, otherwise, i’ll be getting the soapy mister out again to spray them with.

The beetles: live at the Rosemary

Whilst watering my patio, where several plants sit waiting to be potted up, I then noticed some elaborately black and gold-y looking beetles in the replacement Rosemary plant that I had to buy when the big old one didn’t survive the house move ;(.

My new Rosemary plant is being invaded by these pearlescent Rosemary Beetles. Pretty, but they’ll seriously damage it.

It needed a good soak, but curious of what these beetles were, I googled them and discovered that they are specifically Rosemary Beetles (or Chrysolina americana) and have only been known in the UK since the 1990s. The RHS knew all about them, and also have a survey (which i’ve just filled in).
Despite their name, apparently they’re also not restricted to rosemary, and may well spread to Lavender, Sage, and other aromatic plants. I really don’t need that, as I have plenty of those plants, and last weekend was establishing a herb garden area (i’ll show this off soon).

Whilst they spoke of insecticides, I’ve opted at this point for a thorough shake and flick method, and a meet and greet with my shoe, which is still very successful with the slugs and snails. It feels like such a shame to kill them, as they’re quite pretty, but this new rosemary plant is suffering before it’s even been planted out.

Anyway, elsewhere in the garden there are lots of things growing, and I’ll be sharing a few of these – including the first harvest photos, in my next post.

Happy gardening, and if you have to go out in the sun, make sure you wear suncream and/or a hat out there!

Thanks for reading – Andrew.
